Starred Review. Alley thoroughly explains the dynamics of global warming and its negative consequences, and parses the economic benefits of renewable energy. He also forthrightly addresses Climategate, " the politicization of science, and common misperceptions that stoke skepticism about what he convincingly demonstrates is the solid science " of global warming. Alley concludes with suggestions for a measured transition " to a combination of wind, solar, sea, and geothermal power. Alley "s lively and positive Earth operating manual " is the substantial companion book for a new PBS series that will air in April to mark Earth Day.
